The Georgia-Pacific High Performance Component System

Lorient has an exclusive relationship with Georgia-Pacific Corporation to supply a unique high performance fire door component system to door and joinery manufacturers in the UK.

2 GEORGIA-PACIFIC COMPONENT SYSTEM

Lorient has been at the forefront of acoustic, smoke, fire and thermal containment for 35 years, and has a reputation for designing, manufacturing and supplying some of the highest quality products available; supported by a library of test evidence. Georgia-Pacific, with headquarters in Atlanta, is one of the world’s leading manufacturers and marketers of tissue, packaging, pulp, building products and related chemicals. The collaboration of Lorient and Georgia-Pacific, established experts in their respective fields of operation, spans many years. Together, they provide a unique and unrivalled range of products and services, complemented by dedicated technical support.

The Georgia-Pacific engineered non-combustible component system offers a simple and cost effective method of door leaf and frame construction for up to 120 minutes fire performance. The demand for high performance fire doors is growing, largely driven by the requirements of building insurers to limit the damage to compartments of a building in the case of a fire; and to safeguard high value installations, such as plant room, computer and telecoms equipment.

Despite being a high performance door construction, the Georgia-Pacific system still offers freedom of design for specifiers, flexibility for fire engineers and a range of options for door and joinery manufacturers. Finished doors can be a standard 44mm or 54mm thickness, and may be finished in veneered plywood – so manufacturers can produce doors to their client’s unique specification, and the finished doors will appear consistent with others in the building. Single leaf and double leaf combinations are available, to offer freedom of choice throughout a building.

The system comprises:

n GP500 – a low density central core material

n GP1000 – high density elements for the stiles and rails, engineered from non-combustible and non-hazardous products

n Lorient acoustic, smoke and fire seals and glazing systems

Lorient’s System-90 PLUS glazing system features a U-shaped PVC channel encasing sodium silicate intumescent material, retained by a steel ‘Z’ section with a 44mm wide sodium silicate lining. 6mm Pyran® S or FireLite® glass may be used.

Integral to the system are Lorient’s acoustic, smoke and fire seals, including the unique DS profile. Please refer to page 8 for full details.

When the safeguard of valuable equipment in commercial, utility and multiple-occupancy environments is key, Georgia-Pacific doors out-perform – without being unduly heavy or oversized.

Possible ConfigurationsPlease refer to page 8, or contact Lorient Technical Services for details of which configurations are possible with which door constructions

Georgia-Pacific fire door designs have been comprehensively tested at Exova Warringtonfire, conducted in accordance with BS 476: Part 22: 1987. Comprehensive fire testing has established a very wide scope of design variations compatible with the basic door leaf and frame construction. Detail changes from the basic designs are possible by using this library of test evidence, or by scheduling appropriate additional global assessments. Lorient can provide technical support and assistance with this through its own fire testing facility – for example by verifying the compatibility of alternative hardware, door skins or door frame geometry.

Test evidence can be summarised as shown in the following tables:

Test reports and constructional specifications are available to any UK manufacturer who wishes to build doors using the Georgia-Pacific design, under free licence.

The Georgia-Pacific door component system can now be manufactured with long vision panels in double doors, to meet the requirements of Approved Document M.

application without compromise


More applications are now calling for doors to provide acoustic containment, as well as smoke and fire protection. The Georgia-Pacific system, utilising Lorient’s seals, can provide an integrated solution.

When testing for acoustic containment, a door and its seals are tested as a complete assembly. The seals will help to maintain the acoustic performance of the door itself, and over many years of acoustic testing, Lorient’s seals have been proven to be particularly effective for acoustic containment on many different door constructions.

The Georgia-Pacific door construction, with Lorient seals, has been tested for acoustic performance and has achieved an Rw rating of 30dB. Tests were conducted under the conditions of BS EN ISO 10140-2: 2010, and rated according to BS EN ISO 717-1: 1997.

Tests have been carried out on both single leaf and double leaf door assemblies, in either latched or unlatched applications;

also double swing configurations and combinations with steel frames.

The Lorient seals recommended for acoustic containment with the Georgia-Pacific system are:

n LP3506DS combined acoustic, smoke and fire seal (head and jambs of doors)

n LP1006DS combined acoustic, smoke and fire seal at meeting stiles (1 seal, plus 3 x LP1006 fire seal – refer to page 8)

n LAS8003 si or LAS8008 si automatic threshold seal

n LAS1212 Batwing® acoustic and smoke perimeter seal, together with fire seals

For details of alternative choices, please refer to page 8.

Threshold Sealing

The gap between the bottom of the door and the floor is a very commonly overlooked risk area. It is particularly important for smoke protection where the gap is in excess of 3mm, the maximum allowable for a fire/smoke door. Threshold sealing is also essential for effective acoustic containment.

Lorient can provide a range of threshold seals; key benefits of the LAS8003 si and the LAS8008 si automatic threshold seals include:

n High efficiency mechanism which lifts the seal clear of the floor as soon as the door is opened by a few millimetres

n Exceptional acoustic performancen No power connection is requiredn Tested for durability, completing

over 1 million open and close cycles without failure

Product Specifications

All Georgia-Pacific component parts for doors and frames are available ex-stock in the UK from Lorient.

Warnock-Hersey test reports 646-4039 and 646-4080 show that the GP1000 frame stop did not show any visual indications of failure, the door did not show any visual indications of de-lamination or other failure. The screws into the stile and frame remained in place and the hinges were tight to the stile and frame. The reports fully endorse the screw retention characteristics of GP1000 as being at least equal to most hardwoods.

Comparative Screw Retention Values(per 1mm Thread Insertion – No 12 Woodscrew)

Georgia-Pacific GP1000 23.6 Newtons

Timber information from Table 66, BS 5266 PT 11

Screw Retention Tests Slamming Tests (performed in the USA)A typical Georgia-Pacific door construction has also been tested through 1,000,000 slam cycles under the ‘National Window and Door Manufacturers Association – T.M. 7-90’; a test method to determine the physical endurance of wood doors and associated hardware connections under accelerated operating conditions.

Storage and Handling ConditionsGeorgia-Pacific fire door components must be stored flat in dry conditions. There are no critical temperature control requirements. Components should be handled carefully to avoid breakage and sheets of core material in particular should be properly supported around the perimeter rather than just at each end.
